Now, heading into this week's game, he may be Georgia's top reserve at safety. If senior Kelin Johnson can't play due to a knee injury, the Bulldogs will start Reshad Jones and CJ Byrd at safety. Freshman Quintin Banks normally would be the top reserve in that situation but he is out due to a sprained MCL. Sophomore Donavon Baldwin would be next in line, but he's questionable for the game due to a hip injury.
That would leave Williams as the only available backup safety.
"We really hope Kelin is ready to go," Richt said. "If not, it's cutting it kind of close."
Johnson practiced in a green, no-contact jersey Tuesday and declined to speak to the media after practice.
"I thought he moved around pretty good," defensive coordinator Willie Martinez said.
GOOD OMEN: Auburn leads the SEC and is fifth in the nation in points allowed (14.5), but the Bulldogs have a history of screwing up the Tigers' defensive statistics.
In each of the last two seasons, Georgia has posted the highest point total Auburn surrendered that year. In 2005, that was 30 points in a loss. In 2006, it was 37 points in a win.
"I hope that trend continues," Richt said. "The time we hit them might be part of it. I don't know if they had injury troubles by then, or we may have just been improving as the season went along. Two years ago, that might have been our best offensive football game of the year. We played pretty darn good that day offensively. Then last year it could have been our very best game again."
The most Auburn has given up this year is 30 points to LSU. The last time a Tigers opponent scored more than the 37 Georgia posted last year was 2002 (38 against Arkansas).
INJURY UPDATE: Defensive tackle Kade Weston did not practice Tuesday but is expected to play Saturday, defensive coordinator Willie Martinez said.
Running Thomas Brown (collarbone) and wide receiver Tony Wilson (shoulder) practiced in a green jerseys.
Quarterback Matthew Stafford may wear a sleeve on his bruised knee, but it won't affect his play, Richt said. "You could see a little sign that it wasn't 100 percent (on Monday)," Richt said.
